"i really don't want to be on this earth anymore," the harrowing message read. "i'm doing my best to stay here for you but i actually don't know how much longer i can last. all i've ever tried to do was help people. just remember i told you so."

Since posting the cry for help, a number of celebrities and friends have publicly sent the troubled 25-year-old well wishes. His ex, Ariana Grande, even rushed to NBC — where SNL tapes — to be there for Davidson, although reports have stated he explicitly told security to meet her in the lobby and refuse to let her up, so he wouldn't have to see her.

“Lorne has pledged to help all he can, including sending Pete to get help," a source said. "Everyone on the cast is hugely protective of him and were obviously upset — particularly Colin Jost and Michael Che on ‘Weekend Update.’”

Davidson is expected to be on the show's roster in 2019, after its holiday hiatus. According to the source, there has been no talk of him taking time off.
